See the sequences and series quick review video I did here to cover the important must know concepts: kzbin.info/www/bejne/ipubanl3YsljnJo

[@laurenemmett-turner8503]

i dont like the fact. that you go straight into the teaching i feel like you should give some background. Just my opinion.

[@MariosMathTutoring]

I appreciate your input and will consider that for new videos that I film and upload. Thank you Lauren.

Yeah i dont even know what is the difference between geometric sequence arthmetic sequence

Helping me through the eighth grade

[@mamood1783]

when u wish there was a easy tutorial for dummies like me never gonna find one :(

[@jeromeagwu2339]

Could I use a simultaneous equation?

[@nwryy9693]

What if the question asks us to find the first integer in the rth set where the geometric sequence is 1,2,4,8 ?

[@midoriorio7806]

It's 1, 0 is not an integer

[@chrisrides2203]

What if the ratio is division

[@deliasantos8660]

Thanks diko naiintindihan

[@itssohotinhere4615]

how do u get the ratio

[@banjotkohli7734]

Your explanation for why we use or why n-1 is there is not clear, can you please explain in some other way.

[@vister6757]

Because the first value i.e. 3 need not multiply by r. It only starts multiplying at the 2nd term, hence when you want to find the 3rd term u only multiply r twice instead of 3 times (r^2; r^(n-1) where n=3)

[@zainabyahya5485]

pls how do u get that 80

[@kersterineversley5515]

how to work this one 5 , 10,17,26 find the other 3 what am I not understanding

What about this One: a5 = 567, r=3. Find a9. But the Formula is : an=A1 × r^n-¹ ???

Can I ask what if the missing is the ratio and n while the given is the sum the nth term and first term???? I need your reply asap plss reply😭🙏
